He is Belle's son, and Snoopy, Spike , Andy, Olaf , Marbles , Molly and Rover 's nephew. He is much taller and thinner than Belle. Belle's son appears in two Peanuts strips, which were first published on June 29, and June 30, 1976.
Snoopy does not think much of Belle's son. He even writes in a letter to Charlie Brown, that he thinks of him as a disappointment. Snoopy comments that although Belle's son is supposed to be a pure bred beagle, he looks more like the Pink Panther.
